It try to deploy the war to the tomcat5.5.25, and the path is
different.
Use LiftRules.getResource("/images/") to get this information:
In the dev box:
--> Path:Full(file:/G:/project/demo/src/main/webapp/images/
In the tomcat:
--> Path:Full(jndi:/localhost/demo-1.0/images/
The war of the demo path: D:\tomcat_5.5.25\webapps\demo-1.0
So that how can i resolve this problem ?
Cheers,
Neil
